[0002] Existing refrigeration systems used in constant temperature and humidity test chambers are mainly used when the test chamber needs to rapidly cool down the sample to examine its performance under sudden temperature changes.

[0003] However, it lacks an airflow dispersion mechanism during use, and the cold air blown out by the refrigeration system tends to concentrate in certain areas, resulting in localized low temperatures inside the test chamber, which affects the accurate assessment of the overall performance of the equipment. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a refrigeration system for a constant temperature and humidity test chamber. Through the cover and multiple openings on the top, when the active fan blades rotate and blow out airflow, they will drive the driven fan blades to rotate. The rotation of the driven fan blades will drive the baffle with openings to rotate. During the rotation of the baffle, the openings will cyclically open and close different air outlets, which can disperse the concentrated airflow and make the airflow no longer concentrated in one direction, but more evenly diffused throughout the test chamber, which helps to form a stable and uniform temperature field.

[0005] This utility model also provides a refrigeration system for a constant temperature and humidity test chamber, comprising: a chamber body, a shelf fixedly connected to the inner surface of the chamber body, an air inlet pipe extending through the side surface of the chamber body, a semiconductor cooling chip fixedly connected to the inner wall of the air inlet pipe, a bracket fixedly connected to the inner wall of the air inlet pipe, a motor fixedly connected to the inner surface of the bracket, an active fan blade fixedly connected to the output end of the motor, one end of the air inlet pipe connected to a cover, the cover having multiple air outlets, a baffle rotatably connected to the inner surface of the cover, the baffle having an opening, the baffle being movably connected to the air outlets, a rotating rod fixedly connected to the front surface of the baffle, a driven fan blade fixedly connected to the outer wall of the rotating rod, the other end of the air inlet pipe connected to an air inlet box, two cooling plates fixedly connected to the inner surface of the air inlet box, the two cooling plates being staggered, an air inlet on the air inlet box, and a filter screen fixedly connected to the inner wall of the air inlet.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a refrigeration system for a constant temperature and humidity test chamber, comprising: a chamber body 1, a door frame 7 extending through the front surface of the chamber body 1, a cabinet door 8 movably connected to the front surface of the door frame 7, an atomizing nozzle 21 fixedly connected to the inner surface of the chamber body 1, an atomizing device 20 fixedly connected to the side surface of the chamber body 1 (which is an existing mature atomizing device, the specific structure of which will not be described in this document), the output end of the atomizing device 20 communicating with the atomizing nozzle 21, a fan pipe 23 fixedly connected to the inner surface of the chamber body 1, an air inlet provided on the fan pipe 23, a heating plate 17 fixedly connected to the inner wall of the fan pipe 23, a bracket 24 fixedly connected to the inner wall of the fan pipe 23, a motor 25 fixedly connected to the inner surface of the bracket 24, blades 26 fixedly connected to the output end of the motor 25, and a shelf 19 fixedly connected to the inner surface of the chamber body 1.

[0023] Specifically: the air inlet on the fan duct 23 draws in air from the chamber, and the motor 25 drives the blades 26 to rotate, causing the air to flow inside the fan duct 23. When the temperature needs to be increased, the heating plate 17 heats the air, and the heated air is then blown into the chamber to regulate the temperature. The atomizing device 20 atomizes the water and delivers it to the atomizing nozzle 21 through the output end. The atomizing nozzle 21 sprays the water mist into the test chamber, thereby increasing the humidity of the air inside the chamber and regulating the humidity. The shelf 19 is used to place the samples to be tested. The entire system provides a stable test environment for the samples by continuously regulating the temperature and humidity of the air.

[0024] An air inlet pipe 5 extends through the side surface of the housing 1. A semiconductor cooling chip 11 is fixedly connected to the inner wall of the air inlet pipe 5. A heat dissipation hole 2 is provided on the air inlet pipe 5, which is located behind the semiconductor cooling chip 11. A bracket 14 is fixedly connected to the inner wall of the air inlet pipe 5. A motor 13 is fixedly connected to the inner surface of the bracket 14. An active fan blade 12 is fixedly connected to the output end of the motor 13.

[0025] Specifically: Air enters through the intake pipe 5. When the semiconductor cooling chip 11 installed on the inner wall of the intake pipe 5 is energized, it will generate a cooling effect, cooling the passing air to a lower temperature. At the same time, the heat generated by the semiconductor cooling chip 11 will be dissipated through the heat dissipation hole 2, ensuring the normal operation of the semiconductor cooling chip 11. The motor 13 drives the active fan blade 12 to rotate. The wind generated by the rotation of the active fan blade 12 will push the air to flow in the intake pipe 5, and deliver the cooled air to the cover 9.

[0026] One end of the air intake pipe 5 is connected to a cover 9. Multiple air outlets 18 are provided on the cover 9. A baffle 27 is rotatably connected to the inner surface of the cover 9. An opening 22 is provided on the baffle 27. The baffle 27 is movably connected to the air outlets 18. A rotating rod 16 is fixedly connected to the front surface of the baffle 27. A driven fan blade 10 is fixedly connected to the outer wall of the rotating rod 16.

[0027] Specifically: The airflow from the active fan blade 12 will cause the driven fan blade 10 to rotate. The driven fan blade 10 is fixed on the rotating rod 16. Therefore, the rotation of the driven fan blade 10 will drive the rotating rod 16 to rotate. The rotating rod 16 is fixedly connected to the baffle 27. So the rotation of the rotating rod 16 will drive the baffle 27 to rotate inside the housing 9. The baffle 27 is provided with an opening 22. The housing 9 is provided with multiple air outlets 18. During the rotation of the baffle 27, the opening 22 will cycle open and close different air outlets 18. This cycle of opening and closing the air outlets 18 will disperse the concentrated airflow, so that the airflow is no longer concentrated in a certain direction, but diffuses more evenly throughout the test chamber, which helps to form a stable and uniform temperature field.

[0028] The other end of the air intake pipe 5 is connected to the air intake box 3. Two cooling plates 15 are fixedly connected to the inner surface of the air intake box 3. They are used to cool the air to below the dew point temperature and condense the moisture in the air. The two cooling plates 15 are staggered. A refrigeration device 6 is fixedly connected to the side surface of the box 1. It is a mature existing refrigeration device. Its specific structure will not be described in this document. The output end of the refrigeration device 6 is connected to the cooling plate 15. An air inlet is provided on the air intake box 3. A filter screen 4 is fixedly connected to the inner wall of the air inlet.

[0029] Specifically: Outside air enters the air intake chamber 3 through the air inlet. The filter 4 at the air inlet performs preliminary filtration of the incoming air, removing dust, impurities, etc., to ensure that the air entering the system is relatively clean. The air entering the air intake chamber 3 passes through two staggered cooling plates 15. The cooling device 6 provides cooling capacity to the cooling plates 15, lowering their temperature to below the dew point temperature. When the air flows through the cooling plates 15, the water vapor in it condenses into water droplets on the surface of the cooling plates 15, thereby achieving dehumidification of the air, reducing the humidity of the air entering the test chamber, and avoiding interference with the overall humidity.

[0030] Working principle: During use, air enters through the intake pipe 5. The semiconductor cooling chip 11 installed on the inner wall of the intake pipe 5 generates a cooling effect when energized, cooling the passing air to a lower temperature. Simultaneously, the heat generated by the semiconductor cooling chip 11 is dissipated through the heat dissipation holes 2, ensuring the normal operation of the semiconductor cooling chip 11. The motor 13 drives the active fan blade 12 to rotate. The airflow generated by the active fan blade 12 propels the air through the intake pipe 5, delivering the cooled air to the casing 9. The airflow from the active fan blade 12 drives the driven fan blade 10 to rotate. The driven fan blade 10 is fixed to the rotating... The driven fan blade 10 rotates on the rod 16, so the rotation of the rod 16 will drive the rod 16 to rotate. The rod 16 is fixedly connected to the baffle 27, so the rotation of the rod 16 will drive the baffle 27 to rotate inside the cover 9. The baffle 27 is provided with an opening 22, and the cover 9 is provided with multiple air outlets 18. During the rotation of the baffle 27, the opening 22 will cycle open and close different air outlets 18. This cycle of opening and closing the air outlets 18 will disperse the concentrated airflow, so that the airflow is no longer concentrated in a certain direction, but diffuses more evenly throughout the test chamber, which helps to form a stable and uniform temperature field.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
